A rate-dependentperidynamic ceramic model,considering the brittle tensile response,compressive plastic softening and strain-rate dependence,can accurately represent the dynamic response and crack propagation of ceramic ***,it also considers the strain-rate dependence and damage accumulation caused by compressive plastic softening during the compression stage,requiring more computational resources for the bond force evaluation and damage ***,the OpenMP parallel optimization of the rate-dependentperidynamic ceramicmodel is ***,themodules that compute the interactions betweenmaterial points and update damage index are vectorized and ***,the numerical examples are carried out to simulate the dynamic response and fracture of the ceramic plate under normal ***,the speed-up ratio and computational efficiency by multi-threads are evaluated and discussed to demonstrate the reliability of parallelized *** results reveal that the totalwall clock time has been significantly reduced after optimization,showing the promise of parallelization process in terms of accuracy and stability.
